On my real A4000, I've been having problems with crashes or weird behaviour also on MUI 4 and 3.9, which did not occur in 3.8.
For example MCPPrefs would not even open with MUI 4, AmiTradeCenter would crash with a Line 111 Emulator error on various windows.
I am using AFAOS as well, no VisualPrefs however.
Edit: I'm also using CyberGraphX 4 on a PiccoloSD64, testing is being done on a 1024x768 16-bit screen.
